Description

Technical Field

[0001] The utility model relates to a pull tab for a zipper. Background Art

[0002] Generally, a zipper provided on a garment or bag comprises: a plurality of chain elements arranged in two rows and meshing with each other; and a slider which slides along the chain element rows on the chain elements to mesh or disengage the pair of chain element rows. Moreover, a rod-shaped pull tab is mounted on the slider.

[0003] The pull tab is a relatively small component, so a solution has been proposed to install a slightly larger operating component on the pull tab in order to improve operability. For example, Patent Document 1 discloses an extension piece that is installed on a pull tab of a slider that moves up and down along an engaging component in a zipper. In addition, Patent Document 2 discloses a drawstring pull tab that is installed on a slider in a zipper to make the slider easier to operate.

[0004] The pull tab extension of Patent Document 1 includes a handle and a belt. The handle includes: a front panel, a back panel on the back side of the front panel, left and right side panels connecting the front panel and the back panel, a top and a bottom that are further opened, and a stopper that connects the front panel and the back panel inside. The belt forms a ring and is configured in a form that the stopper is received in the ring. Therefore, the handle is not completely hollow, but a stopper like a cylinder that connects the front panel and the back panel is configured in the approximate center.

[0005] In such a pull tab extension, the size of the loop can be freely changed by moving the handle up and down. By making the loop larger, even a person with clumsy hands and poor finger movement can easily move the slider up and down by inserting the finger into the loop. In addition, even if the handle is dropped downward and moved toward the end of the belt, the stopper can prevent the handle from falling off the belt. However, by arranging the stopper inside the handle, the thickness of the handle is inevitably increased, which gives the user the impression of being bulky.

[0006] The pull cord tab of Patent Document 2 has the following structures (i) to (iii).

[0007] (i) a drawstring that passes through a through-hole provided on the slider side of the zipper;

[0008] (ii) an end cap having an engaging portion on the inner side thereof opposite to two ends of the draw cord passing through the through-portion, the engaging portion being engaged with the two ends to accommodate the two ends inside and being mounted on the draw cord;

[0009] (iii) one or more bridge components, which include a through hole for one side of the pull cord passing between the slider and the end cover to pass through, and a through hole for the other side of the pull cord passing between the slider and the end cover to pass through, and are formed of rubber or plastic with rubber-like elasticity.

[0010] In the pull cord tab of Patent Document 2, one or more bridge components are arranged between the end cap and the slider, so that the pull cord tab can be grasped more easily. However, since the user grasps the bridge component to pull the tab, it is difficult to move the slider when the user has clumsy hands or wears gloves.

[0070] Hereinafter, the slide fastener puller which concerns on each embodiment of this invention is demonstrated in detail based on drawings.

[0071] (First embodiment)

[0072] Figure 1 It is a front view of the slide fastener puller according to the first embodiment, and is a diagram showing a state in which the box body is moved to the uppermost position. Figure 2 It is a side view of the slide fastener puller according to the first embodiment, and is a diagram showing a state in which the box body is moved to the uppermost position. Figure 3 It is a front view of the slide fastener puller according to the first embodiment, and is a diagram showing a state in which the box body is moved to the lowest position. Figure 4 It is a side view of the slide fastener puller according to the first embodiment, and is a diagram showing a state in which the box body is moved to the lowest position. Figure 5 yes Figure 4 An enlarged view of the lower part. Figure 6 It is along Figure 1 A cross-sectional view taken along line VI-VI.

[0073] In addition, in this embodiment, the "upward and downward directions" are Figure 1 to Figure 6 The up and down directions in the figure are the same and are the length direction of the slide fastener pull tab 1. Figure 1 to Figure 6 The upper part in the above is the same as that near the side of the slider on which the slide fastener puller 1 is installed. Figure 1 to Figure 6 The bottom of the slide fastener is the same as the side away from the slider of the slide fastener puller 1. Figure 2 , Figures 4 to 6 The left-right direction in the text is the same as the thickness direction of the slide fastener puller 1. The "front-back direction" refers to the front-back direction of the tape 20 constituting the slide fastener puller 1. The "left-right direction" is the same as the thickness direction of the slide fastener puller 1. Figure 1 and Figure 3The left-right direction in the reference numeral corresponds to the “up-down direction” and the “thickness direction” and is also referred to as the width direction of the slide fastener puller 1 or the tape 20 .

[0074] like Figure 1 to Figure 6 As shown, the zipper pull tab 1 of the present embodiment includes: a slider mounting portion 10, which is mounted on a slider not shown in the figure; a belt 20, which is folded in half and forms an annular portion 23 by fixing the two end portions 21, 21 of the belt 20 to the slider mounting portion 10; and a box body 30, which is a movable portion and is mounted on the belt 20 in a manner that can move up and down.

[0075] The slider mounting portion 10 includes a slider fixing portion 11 disposed at the top and fixed to the slider, and a belt fixing portion 13 disposed at the bottom and fixed to both ends 21, 21 of the belt 20. The slider mounting portion 10 is formed of, for example, metal or resin, and the material thereof is not particularly limited. The slider fixing portion 11 and the belt fixing portion 13 are formed integrally.

[0076] like Figure 1 and Figure 3 As shown, the slider fixing portion 11 is roughly annular when viewed from the front, and a slider not shown in the figure can be fixed to the central hole 11a of the slider fixing portion 11. The zipper forming the slider includes, for example: a plurality of chain teeth arranged in two rows and meshing with each other; and a slider that slides along the chain tooth row on these chain teeth while meshing the pair of chain tooth rows or disengaging the pair of chain tooth rows. The slider mounting portion 10 can be fixed to an existing pull tab that has been installed on the slider, or the slider mounting portion 10 can be fixed to the main body of the slider to which the existing pull tab has not been installed.

[0077] like Figure 2 , Figure 4 and Figure 6 As shown, the belt fixing portion 13 is generally inverted U-shaped with an opening at the bottom when viewed from the side. In addition, in addition to the bottom, the belt fixing portion 13 also has two sides ( Figure 2 , Figure 4 and Figure 6 The belt 20 has openings on both sides in the depth direction of the paper. The two end portions 21, 21 of the belt 20 are inserted and fixed inside the belt fixing portion 13 through these openings.

[0078] The belt fixing portion 13 includes: a base portion 15, the thickness direction of which ( Figure 2 , Figure 4 and Figure 6 The upper part of the central part (in the left and right direction) is connected to the slider fixing part 11, and is inclined downward from the central part toward both sides in the thickness direction; and a pair of legs 17, 17, which extend downward from both ends of the base 15 in the thickness direction.

[0079] The pair of legs 17, 17 are arranged in the thickness direction ( Figure 2 , Figure 4 and Figure 6 The legs 17 and 17 are opposed to each other with a gap in the left-right direction (in the left-right direction), and a space is formed between the pair of legs 17 and 17 to accommodate the two end portions 21 and 21 of the belt 20. The pair of legs 17 and 17 are formed with a plurality of protrusions 17a and 17a protruding toward the other leg 17 on the inner surfaces facing each other. The plurality of protrusions 17a and 17a shown in the figure are formed at two locations: the top end portion (lower end portion) of the leg 17 and the middle portion of the leg 17 in the up-down direction, but the number or shape of the protrusions 17a is not particularly limited. The plurality of protrusions 17a engage with the protrusions 21a provided at the two end portions 21 and 21 of the belt 20 as described later, thereby fixing the belt fixing portion 13 and the belt 20.

[0080] Figure 7 It is a stereogram of the belt. Figure 8 is a side view of the belt. Figure 7 and Figure 8 As shown, the belt 20 is a long strip-shaped member formed of an elastic member so as to be bendable. The material of the belt 20 is not particularly limited as long as it has elasticity, and resin materials or rubber materials can be used, and specifically, thermoplastic resins such as Hytrel (registered trademark) can be used.

[0081] The belt 20 includes: a first belt portion 40, one end 41 of which is fixed to the slider mounting portion 10 in the length direction; a second belt portion 50, one end 51 of which is fixed to the slider mounting portion 10 in the length direction; a connecting portion 60, which connects the other end 43 of the first belt portion 40 and the other end 53 of the second belt portion 50; and a protrusion 70, which is formed in the connecting portion 60 and protrudes toward at least one of the front side and the back side of the belt 20. The first belt portion 40, the second belt portion 50, the connecting portion 60 and the protrusion 70 are formed integrally. In addition, Figure 7 and Figure 8 The upper part of the middle is the back side of belt 20, Figure 7 and Figure 8 The lower side of the middle portion is the surface side of the belt 20 .

[0082] The first belt portion 40 and the second belt portion 50 of the illustrated example are mirror-symmetrical with respect to the connecting portion 60 connecting them. However, the first belt portion 40 and the second belt portion 50 do not necessarily need to be mirror-symmetrical.

[0083] The first end portion 41 of the first belt portion 40 and the second end portion 51 of the second belt portion 50 are the two end portions 21, 21 of the belt 20. Figure 7 and Figure 8The lower surface of the belt 20 is provided with a plurality of protrusions 41a, 51a protruding toward the surface side. The plurality of protrusions 41a, 51a shown in the figure are formed at two locations, the top end of one end 41, 51 and the middle part of one end 41, 51, but the number and shape of the protrusions 41a, 51a are not particularly limited. The protrusions 41a, 51a can also be referred to as the protrusions 21a, 21a of the two ends 21 of the belt 20. Figure 2 , Figure 4 and Figure 6 As shown, the protrusions 41a, 51a (protrusions 21a, 21a) engage with the protrusion 17a of the slider mounting portion 10. On the other hand, the back of the end portion 41 of the first belt portion 40 and the end portion 51 of the second belt portion 50 are not formed with a protrusion, and are generally flat, as shown in FIG. Figure 2 , Figure 4 and Figure 6 As shown, they can overlap with each other.

[0084] As described above, the connecting portion 60 is a portion connecting the first belt portion 40 and the second belt portion 50, and is located in the substantially central portion in the length direction of the belt 20. In addition, the connecting portion 60 in this specification is not the point connecting the first belt portion 40 and the second belt portion 50, but a portion having a certain distance in the length direction of the belt 20. Moreover, the first convex portion 71 and the second convex portion 73 constituting the convex portion 70 are provided in a manner separated from each other at the connecting portion 60 having a certain distance in the length direction.

[0085] like Figure 2 , Figures 4 to 6 As shown in FIG. 1 , the belt 20 is folded in half at the center in the longitudinal direction. That is, the belt 20 is folded back at the portion between the first convex portion 71 and the second convex portion 73 that are separated from each other in the connecting portion 60. The folded back portion of the connecting portion 60 is referred to as the folded back portion 61. The first convex portion 71 and the second convex portion 73 are spaced equidistantly from the folded back portion 61 on both sides in the longitudinal direction.

[0086] The convex portion 70 of this embodiment includes a first convex portion 71 and a second convex portion 73 separated from each other in the longitudinal direction of the belt 20. The first convex portion 71 is formed at the other end portion 43 of the first belt portion 40 constituting the connecting portion 60, and protrudes toward at least one of the front side and the back side of the first belt portion 40. The second convex portion 73 is formed at the other end portion 53 of the second belt portion 50 constituting the connecting portion 60, and protrudes toward at least one of the front side and the back side of the second belt portion 50.

[0087] In this embodiment, the first convex portion 71 includes a first front convex portion 71a and a first back convex portion 71b protruding toward the front and back sides of the first band portion 40, and the second convex portion 73 includes a second front convex portion 73a and a second back convex portion 73b protruding toward the front and back sides of the second band portion 50. Figure 2 , Figures 4 to 6 As shown, the first front side protrusion 71a and the second front side protrusion 73a are formed on the outer peripheral side of the annular portion 23 when the belt 20 is folded in half at the folding portion 61, and the first back side protrusion 71b and the second back side protrusion 73b are formed on the inner peripheral side of the annular portion 23 when the belt 20 is folded in half.

[0088] In the length direction and width direction of the belt 20, the length of the first back convex portion 71b is substantially equal to the length of the first front convex portion 71a, and the length of the second back convex portion 73b is substantially equal to the length of the second front convex portion 73a. Figure 5 As shown, in the front and back directions of the belt 20, the height H2 of the first back convex portion 71b is smaller than the height H1 of the first front convex portion 71a (H2

[0089] Fig. 9 It is a three-dimensional diagram of the box. Fig.10 This is a top view of the box from the top and bottom. Fig. 9 and Fig.10 As shown, the box body 30 is generally in the shape of a rectangular parallelepiped. The box body 30 is formed of, for example, a metal material or a resin material, but the material is not particularly limited. The box body 30 is provided with a through hole 31 at its center, and the cross section of the through hole 31 is generally rectangular and penetrates the box body 30 in the up and down direction. Therefore, the box body 30 has four faces around the through hole 31. That is, the box body 30 includes: a left-right first face 32 and a left-right second face 33 that are arranged in a manner separated from each other in the left-right direction, and a thickness direction first face 34 and a thickness direction second face 35 that are arranged in a manner separated from each other in the thickness direction.

[0090] The first belt portion 40 and the second belt portion 50 of the folded belt 20 are folded in the front and back direction of the belt 20 ( Figure 1 and Figure 3 In the paper depth direction, Figure 2 , Figures 4 to 6 ) is inserted into the through hole 31 in an overlapping state. Therefore, it is necessary to set the size of the through hole 31 so that the first belt portion 40 and the second belt portion 50 can be inserted therein. Figure 1 and Figure 3 As shown, the width of the through hole 31 in the left-right direction is set to be larger than the width of the belt 20 (the first belt portion 40 and the second belt portion 50) in the left-right direction. Figure 5 As shown, in the front-back direction of the belt 20 , the height h1 of the through hole 31 is set to be larger than the total height H5+H6 of the height H5 of the first belt portion 40 and the height H6 of the second belt portion 50 ( h1 > H5+H6 ).

[0091] ​In this way, when the first belt portion 40 and the second belt portion 50 are inserted into the through hole 31, the one end portions 41 and 51 provided with the protrusions 41a and 51a are located above the through hole 31, and the connecting portion 60 provided with the first protrusion 71 and the second protrusion 73 is located below the through hole 31.

[0092] The first end portion 41 of the first belt portion 40 and the second end portion 51 of the second belt portion 50 above the through hole 31 are inserted into the receiving space between the pair of leg portions 17, 17 of the belt fixing portion 13 in a state where the planar portions of the back surfaces of the first end portions 41, 51 overlap each other. The belt fixing portion 13 is inserted into the receiving space by moving the belt fixing portion 13 in the left and right directions ( Figure 1 and Figure 3 In the left and right directions, Figure 2 , Figures 4 to 6 The belt fixing portion 13 and the belt 20 are fixed by inserting the belt fixing portion 13 into the opening. After the one end portion 41, 51 is inserted into the receiving space, the pair of legs 17, 17 are pressed toward each other. As a result, the plurality of protrusions 17a, 17a of the pair of legs 17, 17 engage with the protrusions 41a, 51a provided at the one end portion 41, 51, and the belt fixing portion 13 and the belt 20 are fixed.

[0093] In addition, if Figure 5 As shown, in the front-back direction of the belt 20, the total height H1+H2+H3+H4+H5+H6 of the height H5 of the first belt portion 40, the height H1+H2 of the first convex portion 71, the height H6 of the second belt portion 50, and the height H3+H4 of the second convex portion 73 is higher than the height h1 of the through hole 31 of the box body 30 (H1+H2+H3+H4+H5+H6>h1). By setting the height of each part in this way, the box body 30 can be prevented from falling downward as described later.

[0094] In the slide fastener puller 1 configured as described above, the size of the loop portion 23 of the tape 20 is changed by moving the box body 30 up and down, and the puller 1 can be used according to the needs of the user.

[0095] For example, Figure 1 and Figure 2 As shown, when the box body 30 is moved toward the upper slider mounting portion 10, the ring portion 23 of the belt 20 becomes larger, so the inside of the ring portion 23 can be hooked with fingers. Therefore, even a user with clumsy hands or a user wearing gloves can easily pull the pull tab.

[0096] In addition, even based on Figure 1 and Figure 2 Even when the box body 30 is further moved upward in the state shown, the box body 30 does not fall off upward due to interference with the belt fixing portion 13 of the slider mounting portion 10 .

[0097] In addition, Figure 1 and Figure 2 In the case where the box body 30 is not pulled downward and is in a no-load state, the box body 30 will not move downward naturally. This is because the annular portion 23 of the belt 20 moves downward in the thickness direction ( Figure 2 , Figures 4 to 6 The diameter is expanded in the left-right direction), so the downward movement of the box body 30 is restricted at the position where the lower end of the through hole 31 contacts the annular portion 23.

[0098] based on Figure 1 and Figure 2 In the state shown in FIG. 1 , when the user holds the box body 30 and moves it toward the lower connecting portion 60 on the opposite side of the slider mounting portion 10, as shown in FIG. Figure 3 to Figure 6 As shown in the figure, the annular portion 23 of the belt 20 is elastically reduced in diameter and deformed to enter the through hole 31 of the box body 30. As a result, the first belt portion 40 and the second belt portion 50 constituting the annular portion 23 of the belt 20 move closer to each other, and the annular portion 23 is deformed in the thickness direction ( Figures 4 to 6 The zipper pull tab 1 is thinner in the left-right direction and longer in the up-down direction. Thus, the grippable portion of the belt 20 can be lengthened. In this case, by gripping the belt 20 or the box body 30, the zipper pull tab 1 can be pulled.

[0099] exist Figure 3 to Figure 6 In the state shown, the belt 20 is folded back at the folding portion 61, but since the first convex portion 71 and the second convex portion 73 are spaced equidistantly from the folding portion 61 on both sides in the length direction, the first convex portion 71 and the second convex portion 73 are close to or in contact with each other. Figure 5 In the figure, an example is shown in which the first dorsal convex portion 71b of the first convex portion 71 and the second dorsal convex portion 73b of the second convex portion 73 face each other with a small gap therebetween. When the box body 30 is moved to the lowest position (connecting portion 60 side), the first dorsal convex portion 71b and the second dorsal convex portion 73b can face each other with a gap therebetween or can contact each other.

[0100] In this way, since the first convex portion 71 and the second convex portion 73 are separated from each other in the longitudinal direction of the belt 20, the connecting portion 60 of the belt 20 can be easily elastically deformed. Therefore, when the box 30 is moved to the connecting portion 60 side opposite to the slider mounting portion 10, the connecting portion 60 can be easily elastically deformed and folded, so that the ring portion 23 of the belt 20 can be made thinner and closer to a plate shape. Therefore, unlike the pull-tab extension member described in Patent Document 1, it does not give the impression of being bulky, and a thin slide fastener pull tab 1 with excellent appearance can be realized.

[0101] In addition, in the front and back direction of the belt, the height H2 of the first back convex portion 71b is smaller than the height H1 of the first front convex portion 71a (H2

[0102] In addition, when the box body 30 is moved to the connecting portion 60 side opposite to the slider mounting portion 10, the connecting portion 60 is elastically deformed and folded, and the first back side convex portion 71b of the first convex portion 71 and the second back side convex portion 73b of the second convex portion contact each other or face each other with a small gap. Therefore, the first convex portion 71 and the second convex portion 73 prevent the belt 20 from entering the through hole 31 of the box body 30, so that the box body 30 can be prevented from falling downward.

[0103] In particular, in the front and back directions of the belt 20, the total height H1+H2+H3+H4+H5+H6 of the height H5 of the first belt portion 40, the height H1+H2 of the first protrusion 71, the height H6 of the second belt portion 50 and the height H3+H4 of the second protrusion 73 is set to be greater than the height h1 of the through hole 31 of the box body 30 (H1+H2+H3+H4+H5+H6>h1), so that the box body 30 can be more reliably prevented from falling off downward.

[0104] In addition, Figure 5 , an example in which a vertical gap S exists between the first front side convex portion 71a of the first convex portion 71 and the second front side convex portion 73a of the second convex portion 73 and the box body 30 is shown. Even when the box body 30 is moved to the lowest position (the connecting portion 60 side), it is preferable to adjust the elastic force or shape of the belt 20 to form the vertical gap S as described above. By inserting the user's fingernail into the vertical gap S, the box body 30 can be moved toward the upper slider mounting portion 10 side without relying on vision.

[0105] In addition, although not shown, it is preferred that the total height H1+H2+H3+H4+H5+H6 of the height H5 of the first belt portion 40, the height H1+H2 of the first convex portion 71, the height H6 of the second belt portion 50, and the height H3+H4 of the second convex portion 73 is equal to the height h2 of the box 30 (H1+H2+H3+H4+H5+H6=h2) in the front and back direction of the belt 20. Thus, the height of the portion of the belt 20 provided with the first convex portion 71 and the second convex portion 73 is equal to that of the box 30, so that a slender impression can be given.

[0106] ​(Second embodiment)

[0107] Next, the zipper pull tab 1 according to the second embodiment is described. The zipper pull tab 1 of this embodiment is different from the first embodiment only in the structure of the protrusion 70, and the other structures are substantially the same as those of the first embodiment. The same parts are marked with the same reference numerals in the drawings, and their descriptions are omitted or simplified.

[0108] Fig.11 It is a front view of the slide fastener puller according to the second embodiment, and is a diagram showing a state in which the box body is moved to the uppermost position. Fig.12 It is a side view of the slide fastener puller according to the second embodiment, and is a diagram showing a state in which the box body is moved to the uppermost position. Fig.13 It is a front view of the slide fastener puller according to the second embodiment, and is a diagram showing a state in which the box body is moved to the lowest position. Fig.14 It is a side view of the slide fastener puller according to the second embodiment, and is a diagram showing a state in which the box body is moved to the lowest position. Fig.15 yes Fig.14 An enlarged view of the lower part. Fig.16 It is along Fig.11 Cross-sectional view along line XVI-XVI. Fig.17 yes Fig.16 An enlarged view of the lower part. Fig.18 It is a stereogram of the belt.

[0109] like Figures 11 to 18 As shown, the belt 20 of this embodiment has a convex portion 70 similar to the first embodiment, and the convex portion 70 is formed on the connecting portion 60 and protrudes toward at least one of the front side and the back side of the belt 20. On the other hand, the convex portion 70 of this embodiment is different from the first embodiment in that it does not include the first convex portion 71 and the second convex portion 73, but has a back convex portion 70b.

[0110] In the first embodiment, the first convex portion 71 and the second convex portion 73 are arranged in a manner separated from the folding portion 61 of the connecting portion 60, so that elastic deformation is easily generated when the box body 30 is moved downward, so that the belt 20 is easily folded at the folding portion 61. In contrast, in the present embodiment, the convex portion 70 (back convex portion 70b) is provided at the folding portion 61, so that when the box body 30 is moved downward, the belt 20 does not bend greatly at the folding portion 61, and the connecting portion 60 including the folding portion 61 is kept at a height that does not enter the through hole 31.

[0111] That is, Fig.17As shown in FIG. 1 , when the box body 30 is moved toward the connecting portion 60 on the opposite side of the slider mounting portion 10, the connecting portion 60 is elastically deformed and folded, but the bending of the connecting portion 60 is restricted because the back convex portion 70b is provided on the folding portion 61. Fig.17 In the left-right direction), the height H7 of the connection portion 60 can be maintained above the height h1 of the through hole 31 (H7 ≥ h1). Thus, the box body 30 can be prevented from falling downward from the connection portion 60 side.

[0112] In addition, as long as the function of limiting the bending at the folded portion 61 is provided, the convex portion 70 may include only the back convex portion 70b protruding toward the back side, or only the front convex portion protruding toward the front side, or both the back convex portion and the front convex portion. However, compared with providing the front convex portion as the outer side of the bend, providing the back convex portion as the inner side of the bend can more effectively limit the bending of the folded portion 61.

[0113] In addition, the present invention is not limited to the configuration exemplified in the above-mentioned embodiment, and can be appropriately modified within a range not departing from the gist of the present invention.

[0114] For example, a recessed portion (not shown) that can be engaged with the convex portion 70 of the belt 20 can also be provided at the lower portion of the connecting portion 60 side of the box body 30. In this way, the convex portion 70 can be engaged with the concave portion to limit the movement of the box body 30 to the connecting portion 60 side, so that the box body 30 can be more reliably prevented from falling off downward.

[0115] As described above, the following matters are disclosed in this specification.

[0116] (1) A zipper pull tab, the zipper pull tab 1 comprising:

[0117] A slider mounting portion 10, which is mounted on the slider;

[0118] a belt 20 folded in half, and having both ends of the belt 20 fixed to the slider mounting portion 10 to form an annular portion; and

[0119] The moving part 30 is mounted on the belt 20 so as to be movable up and down.

[0120] The belt 20 comprises:

[0121] A first belt portion 40, one end portion 41 of which is fixed to the slider mounting portion 10;

[0122] A second belt portion 50, one end portion 51 of which is fixed to the slider mounting portion 10;

[0123] a connecting portion 60 connecting the other end portion 43 of the first belt portion 40 and the other end portion 53 of the second belt portion 50; and

[0124] The convex portion 70 is formed on the connecting portion 60 and protrudes toward at least one of the front side and the back side of the belt 20.

[0125] The moving portion 30 has a through hole 31 penetrating the moving portion 30 , and can move up and down on the belt 20 in a state where the first belt portion 40 and the second belt portion 50 are inserted into the through hole 31 .

[0126] According to this structure, since a movable portion 30 is provided that can move up and down on the belt 20 when the first belt portion 40 and the second belt portion 50 are inserted into the through hole 31, the size of the annular portion of the belt 20 is changed by moving the movable portion 30, so that it can be used according to the needs of the user.

[0127] For example, when the movable portion 30 is moved toward the slider mounting portion 10, the annular portion of the band 20 becomes the largest, so the annular portion can be hooked with a finger. Therefore, even a user with clumsy hands or a user wearing gloves can easily pull the pull tab 1.

[0128] On the contrary, when the moving part 30 is moved to the connecting part 60 side opposite to the slider mounting part 10, the annular part of the belt 20 becomes smaller, and the grippable part of the belt 20 can be lengthened. In this case, the pull tab 1 can be pulled by gripping the belt 20 or the moving part 30.

[0129] Furthermore, in the belt 20 , a convex portion 70 is formed in the connecting portion 60 on the opposite side to the slider mounting portion 10 .

[0130] Therefore, for example, if the portion of the belt 20 where the projection 70 is formed is set to a height that cannot enter the through hole 31 of the moving portion 30 , it is possible to prevent the moving portion 30 from falling off from the connecting portion 60 side.

[0131] In addition, for example, by providing the convex portion 70 to limit the elastic deformation amount of the connecting portion 60 including the folded portion of the belt 20, the connecting portion 60 does not bend greatly, and the connecting portion 60 maintains a height that does not enter the through hole 31 of the moving portion 30. In this case, the moving portion 30 can also be prevented from falling off from the connecting portion 60 side.

[0132] (2) In the slide fastener puller 1 described in (1), the convex portion 70 includes a first convex portion 71 and a second convex portion 73 that are separated from each other,

[0133] The first protrusion 71 is formed at the other end portion 43 of the first belt portion 40 and protrudes toward at least one of the front side and the back side of the first belt portion 40.

[0134] The second protrusion 73 is formed at the other end portion 53 of the second belt portion 50 , and protrudes toward at least one of the front side and the back side of the second belt portion 50 .

[0135] According to this structure, since the first convex portion 71 and the second convex portion 73 are separated from each other, the connecting portion 60 of the belt 20 can be easily elastically deformed (easy to bend). Therefore, when the moving portion 30 is moved to the connecting portion 60 side opposite to the slider mounting portion 10, the connecting portion 60 can be easily elastically deformed and folded, so that the annular portion of the belt 20 can be made very thin and close to a plate shape. Therefore, unlike Patent Document 1, it does not give the impression of being bulky, and a thin pull tab 1 with excellent appearance can be realized.

[0136] (3) In the slide fastener pull tab 1 described in (2), the first convex portion 71 includes a first front convex portion 71a protruding toward the front side of the first tape portion 40 and a first back convex portion 71b protruding toward the back side of the first tape portion 40,

[0137] The second convex portion 73 includes a second front convex portion 73 a protruding toward the front side of the second belt portion 50 and a second back convex portion 73 b protruding toward the back side of the second belt portion 50 .

[0138] According to this structure, when the movable part 30 is moved the most toward the connecting part 60 side opposite to the slider mounting part 10, the connecting part 60 is elastically deformed and folded, and the first dorsal convex part 71b of the first convex part 71 and the second dorsal convex part 73b of the second convex part 73 contact each other or face each other with a small gap therebetween.

[0139] Therefore, the first convex portion 71 and the second convex portion 73 prevent the belt 20 from entering the through hole 31 of the moving portion 30 , so that the moving portion 30 can be prevented from falling off.

[0140] (4) In the slide fastener pull tab 1 described in (3), in the front-back direction of the tape, the height H2 of the first back-side protrusion 71b is smaller than the height H1 of the first front-side protrusion 71a, and the height H4 of the second back-side protrusion 73b is smaller than the height H3 of the second front-side protrusion 73a.

[0141] According to this structure, when the movable part 30 is moved most toward the connecting part 60 side opposite to the slider mounting part 10, the range of the folded part of the belt 20 between the first protrusion 71 and the second protrusion 73 can be narrowed, so that it can be close to a plate shape, giving a slender impression.

[0142] (5) In the zipper pull tab 1 described in any one of (2) to (4), in the front and back directions of the tape, the total height H1+H2+H3+H4+H5+H6 of the first tape portion 40, the first protrusion 71, the second tape portion 50 and the second protrusion 73 is greater than the height h1 of the through hole 31 of the movable portion 30.

[0143] According to this configuration, the first convex portion 71 and the second convex portion 73 can more reliably prevent the belt 20 from entering the through hole 31 of the moving portion 30 , and thus the moving portion 30 can be more reliably prevented from falling off.

[0144] (6) In the slide fastener pull tab 1 described in (1), the connecting portion 60 has a folded portion 61 which is a portion folded back when the tape 20 is folded in half,

[0145] The folded portion 61 is provided with the convex portion 70 that protrudes toward at least one of the front side and the back side of the belt 20 .

[0146] According to this structure, since the folded portion 61 becomes thicker due to the provision of the convex portion 70, its elastic deformation amount is reduced and it becomes difficult to bend. As a result, the connecting portion 60 having the folded portion 61 can maintain a height that does not enter the through hole 31 of the moving portion 30. In this case, the moving portion 30 can also be prevented from falling off from the connecting portion 60 side.
